讨论：药害事件定义是什么？

药害(drug misadventures)是用药固有的医源性意外风险，它使用药者因接受或遗漏用药而受到往往是非预期的、不能接受的伤害，其发生与原有疾病有关或无关，可能涉及人为及／或系统的差错、免疫学或特异质反应。与药物不良反应(合格药品正常量用法的意外有害后果)相比，除两者都包括过敏与特异质之外，药害还可能与不合格药品(成分、包装、调配、标示问题)与不正常用法(适应症、用法、用量有误)有关；表现可能明显(休克)或隐蔽(耐药菌)。

药害事件在Drug information: a guide for pharmacists中的定义：
There is potential for unexpected adverse events, including errors in prescribing, dispensing, and administering medications, idiosyncratic reactions, and other adverse effects. These events can all be described as medication misadventures.
Medication misadventure is a very broad term. It refers to any iatrogenic hazard or incident associated with medications. A medication misadventure may or may not cause an injury to a patient. All adverse drug events (ADEs), adverse drug reactions (ADRs), and medication errors fall under the umbrella of medication misadventures. An ADE is the next broadest term. It refers to any injury caused by a medicine. An ADE refers to all ADRs, including allergic or idiosyncratic reactions, as well as medication errors that result in harm to a patient. ADRs and medication errors are the most specific terms. ADRs refer to any unexpected, unintended, undesired, or excessive response to a medicine. Drug-drug interactions can also fall into the category of ADRs. A medication error is any preventable event that has the potential to lead to inappropriate medication use or patient harm.

赞同10楼的说法，全面、详细！

俺认为属于，只要与药物有关，对人体健康造成损害的事件都属于药害事件

22 楼的图指出了它们之间的关系，清楚的说明了问题........

lockzhang的回复很权威，也很全面，就是medication misadventures的确切含义不是很好理解，是不是应该概指整个医疗活动啊？
